SPECIFICATION forming part of Letters Patent No. 601,168, dated March22, 189s.

A Application filed May 27, 1897. Serial No. 638,459. (No model.)

To all whom it may concern.'

Be it known that I, ELI THOMPSON PRIEST, a citizen of thevUnited States,residing at Rising Star, in the county of Eastland and State of Texas,have invented a new and useful Insect-Destroyer, of which the followingis a specication.

The invention relates to improvements in insect-destroyers.

The object of the present invention is to improve the construction' ofthat class-of devices which generate steam for the destruction ofinsects and to provide a simple, strong, and durable insect-destroyerwhich will be capable of containing a large quantity of water and ofpresenting a largeheating-surface, whereby steam is quicklygenerated.

The invention consists in the construction and novel combination andarrangement of parts, as hereinafter fully described, illus# trated inthe accompanying drawings, and pointed out in the claims heretoappended.

In the drawings, Figure 1 is a perspective View of an insect-destroyerconstructed in accordance with this invention. Fig. 2 is a centralvertical sectional view.

Like numerals of reference designate corresponding parts in both figuresof the drawings.

1 designatesa cylindrical fire-pot constructed of suitable metal andpreferably having its bottom 2 integral with the sides and provided withan opening 3, which is normally covered by a slide 4, adapted to permitashes to be readily removed without necessitating the removal of a grate5. The grate 5 is detachably arranged within the tire-pot 1, which isprovided at a point below the grate with a series of draft-openings 6.

The necessary heat may be obtained by placing live coals' on the grate5, which may Vbe readily removed when burned out; but, if

fuel, and aninsect-destroyer equipped with a grate and a pan may useeither live coals or coal-oil. The diameter of the pan 7 is less thanthat of the fire-pot in order to provide upon the upper edges of thelire-pot.

an intervening annular space between the periphery of the pan and thewalls of the irepot to receive the annular supporting-liange of thegrate.

A spherical boiler or steam-generator 8 is arranged at the top of thelire-pot and extends partially within the same, being provided withanexterior supporting-rib 9, which rests The boiler or generator, which isconnected with the ure-pot by a hinge lO, consists of inner and outersubstantially spherical shells 11 `and 12, a conical bottoln piece 13connecting the shells at that point, and a cylindrical tube or chimney14 connecting the inner and outer shells at the top and extending abovethe boiler or generator. The opening of the outer shell 12 is ofsufficient diameter to permit the inner shell or lining to be readilypassed throughitin assembling the parts, and the inner faces of theconical bottom piece, inner shell, and chimney provide a large area ofheating-surface, and the boiler or generator, which has a large capacityfor water, thoroughly exposes it to the action of the heat and steam isquickly generated.

' The tire-pot is provided with a'handle 15, and the boiler or generatoris provided at a point diametrically opposite the handle with adischarge-spout 16, and the hinge is arranged at one side of the device,so that there is no liability of the boiler or generator swingingoutward in handling the device.

The boiler is provided with a strainer l5, preferably constructed ofwire gauze and soldered or otherwise secured to `the inner face of theouter shell, as clearly illustrated in Fig. 2 of the accompanyingdrawings. The strainer covers the inner end of the spout and preventsthe same from becoming clogged and interfering with the discharge of thesteam through accumulation in the boiler.

The spout, which is preferably constructed tapering, as shown, isadapted to receive a tube or hose when the device is constructed on alarge scale. The hose will enable steam Ioo provided for introducingwater into the boiler or generator, and this tube is normally keptclosed by a plug or stopper 1S.

The fire-pot is provided with legs I9, which support the bottoni above acarpet or other supporting-surface, so that the device may be rested ona table, cha-ir, or the like without injuring the furniture.

rlhe device is used by moving the spout along crevices in furniture, andsteam is injected into the same, quickly destroying bedbugs and otherinsects.

It will be seen that the insect-destroyer is simple, strong, anddurable, that the boiler or steam-generator has a large capacity forwater and at the same time exposes its contents to a large amount ofheating-surface, and that either live coals or coal-oil may be employedas a fuel.

l. An insect-destroyer comprising a fire- 4pot, and a boiler orgenerator composed of inner and outerspherical shells, the conicalbottom piece connecting the inner and outer shells at the base, and thechimney-tube connecting them at the top, said boiler or generator beingprovided with a discharge-spout, substantially as described.

2. An insect-destroyer comprising a firepot, a boiler or generatormounted at the top of the fire-pot, a concave pan centrally fixed to thebottom of the iire-pot and designed to receive ashes or similarmaterial, saturated with oil, to provide an oil-burner, said pan beingof less diameter than the fire-pot and forming an intervening annularspace between its periphery and the walls of the fire-pot, and aremovable grate located above the pan and provided at its periphery witha depending annular supportingi'lange -located in the space between thepan and the walls of the fire-pot, substantially as and for the purposedescribed.

In testimony that I claim the foregoing as my own I have hereto afiiXedmy signature in the presence of two witnesses.

ELI THOMPSON PRIEST.
